Frequently asked questions
Common questions people ask before using this tool.
What is a QR code used for?
QR codes encode URLs, plain text, Wi-Fi credentials, contact info (vCards), or payment details so phones can scan and open them instantly. They are common on posters, menus, product packaging, and business cards to bridge print and mobile web.
Can I create a QR code for free?
Yes. Enter your URL or text, choose size options, then download the image. Test the code with your phone before printing large batches to catch broken links or typos that would make codes unreadable.
Will my QR code expire?
The QR image itself never expires — it encodes static data. However, the link or content it points to can break if you change URLs, delete pages, or shut down domains. Use stable short links for printed marketing materials with long shelf lives.
Are QR codes safe to scan?
The format is neutral — safety depends entirely on the destination. Only scan codes from trusted sources, and be cautious of QR codes in unexpected places. Modern smartphone QR scanners preview the URL before opening so you can check before tapping.
What resolution should I use when printing a QR code?
Download the largest version available and print at 300 DPI or higher. Always include a quiet zone (white margin of at least 4 modules wide) around the code — scanners need this clear space to detect the code's boundaries reliably.
How much data can a QR code hold?
QR codes can store up to about 7,089 numeric characters or 4,296 alphanumeric characters. For URLs, keep them as short as possible — long URLs increase code density, making the code harder to scan, especially when printed at small sizes.
